8.41 Use Hund's rule to derive the electronic configuration of Ce3+ ion, and calculate its magnetic moment on the basis of 'spin-only' formula.
8.41 Use Hund's rule to derive the electronic configuration of Ce3+ ion, and calculate its magnetic moment on the basis of 'spin-only' formula.
8.41 The atomic number of Cerium (Ce) is Z = 58.
The electronic configuration of 58Ce= [Xe]54 4f1 5d1 6s2
And, the electronic configuration of Ce3+= [Xe]54 4f1 , i.e., there is only one unpaired electron, i.e., n = 1.
Now, the magnetic moment on the basis of spin only formula is given as:
μ = √n(n+2) BM
